1. C.AppuleiusDecianus was tribune of the people in B. C. 90. In that year he brought a charge against L. Valerius Flaccus, the nature of which is unknown. He also brought an accusation against L. Furius, one of the tribunes of the year previous, who opposed the recall of Metellus Numidicus. It seems to have been on this occasion that he lamented before the public assembly the fate of L. Appuleius Saturninus and Servilius Glaucia, and endeavoured to create disturbances to avenge their death. In consequence of these proceedings he himself was condemned, and went into exile to Pontus, where he engaged in the service of Mithridates. (Cic. pro Ralbir. perd. 9, pro Flacc. 32; Schol. Bobiens. p. 230, ed. Orelli; V. Max. 8.1.2; Appian, App. BC 1.33.)
